GRS-17 is a 50% phenyl methylpolysiloxane phase. The presence of the 50% phenyl groups increases the overall “polarity” of the phase and enhances the selectivity of induced dipole interactions resulting in greater retention of aromatic solutes. The GRS-17 phase is widely used as an EPA Method confirmation column and provides for efficient separations of PAHs, and biomedical samples such as drugs, sugars and steroids.
- Bonded and crosslinked
- Medium polarity
- Comparable to OV-17
- Similar phases: DB-17, Rtx-50, SPB-50, AT-50, HP-17, HP-50+, CPSil-20CB
- USP Phase Specification: G3
GRS-17, (50% Phenyl) Methylpolysiloxane columns are available in all standard column I.D.’s and lengths.
